Correct, don't you splinter with xxx, Jxxxx, x, KQxx having given a negative to 2♣ when partner bids 2♠ ?

I didn't assume that jillybean plays 2D as negative.

I prefer to play that the splinter still shows 4-card support. When you have shortness, the fourth trump is still big, even when opener has long trumps. With 3-card support, I make a simple raise.

We have shown spades, hearts and the lack of KC must suggest to partner that we have a void, obviously a club void.

Is partner going to be able to make an intelligent decision based on this information, though? Opener is the only one that will be able to place the contract, and even that is iffy. The only thing you care about really is the spade king, though, and the only way (without GSF) you have at this point to get at it is via keycard.

I didn't assume that 2D was negative either, just waiting.

If the splinter shows 4 card support, then KC and bidding 7S opposite at least 1 becomes my choice as well.

Here's the full hand, I was kibitzing a jec match.

At the other table they stopped in 6♠ after

1♠-3♠(9-11)
4N:5♥
6♠

At the "other table" the problem was not the 1S opening bid. It was the bull in the China shop 4NT bid afterward. Can there really be someone who doesn't use 3NT/3S (or something else) to check for side shortness?

At that level I agree. Could it have been some World Class players without much partnership discussion? There still has to be a better way than 4nt.

I'm also surprised that Jec's partner bid the grand after finding a parking place for his small heart but NOT finding the ♠K. I would think the splinter is on with 4 trumps lacking it on this (aproximate) shape.

Maybe another non-solid partnership going on the "he's got it or it's onside" principal.

If my partner splintered, I would roll our 6♣EKB. In my partnerships, I am on firmer ground with my responses than GSF responses, which seems to come up more on internet bridge forums than in real life.
